Ported + Polished Heads
 

While waiting for the body shop to schedule my car in to finish up the custom rear metal flares I figured to bring the car in to my trusted indie shop to get the head bolts and lifters replaced. During this repair I had the heads ported, polished, valve job and resurface done. Won't have a dyno for awhile till the car is done completely. Meantime I got photos of the port n polish. I will have pics of valve job later.

The port and polish ran me $1300
The valve job and resurface ran me $500

Wow. That looks pretty good. Mine goes in next week, but my shop advised me not to do the PnP as the heads are pretty good overall and said I might lose some power down low for not a significant gain up top. I'm definitely interested in your gains. Has anyone tried the dimpled heads? I've read up on the theory behind them but have seen very few people use them. Not sure if that's due to cost/benefit or if they don't actually work in the real world.

Damn they did a solid job by the looks of it, did you do a dyno prior for a baseline? Interested in what results you end up seeing

This guy's is a gun I have seen his work on Instagram

So your the lucky fellow that got these ported heads :)

Take to to a flow bench and see how.much they flow for us?

Also since you went down this road make sure you get black series buckets and rev that sucker to 7800 :)

Yoh first time something different than the usual Jap cylinder head work I have seen. They really done a marvelous job on those heads of yours.

My last dyno was 485/444. So we will get results on what this does. The dyno place was booked this week or else I would have made a stop there before handing the car over to the body shop to finish what has been a long wait. Haven't driven the car since August.

Yep this guy is local and believe it or not this was all done by hand in his garage.

I didn't know the BS lifters were any better. I've done some searches and even read in AMGs head bolt thread that they are not much of a differenace as the design hasn't changed. Too late anyways the lifters were ordered and already soaked in oil. Car will be fully assembled tomorrow.

Flow benching would cost me $100 a cylinder not looking to spend anymore money. I'll just be happy to break into the 500s finally.

I've been following him and want to send my heads to him all the way from Australia

His work is amazing mate

Yes black series buckets are TI and can take more abuse and more RPM

Keep me posted man

Im sure he will be flattered to hear that. I'm surprised you found out about him considering these to be the first Mercedes c63 heads he's ported. He did say himself though these are the biggest ports he has ever seen.

That looks incredible, amazing work

Please update this thread once you have her assembled and on the dyno, keen to see the numbers

Did he do any work on the comb chamber? Are you sticking w stock compression?

Are you going to put some custom or am cams in?

I wonder how the port matching at the headers looks and intake manifold looks stock? I suspect pretty good. Unlike domestics where there are gains there.

My friend follows him and he tagged me

There actually to good to bolt on to the car lol

Ahhhh I love it man, looks great! Some flowbench cfm figures would be lovely if you can get them...if not...we'll make do with whp when you get a chance :)


Ahhh what, really?? Damn, if I knew this, I would have bought those instead. So....regular SLS buckets can't do much more than what normal M156 buckets can do?

Are you referring to 'the throat'? If so, I'd like to know this also.

Compression....more of it would be nice, but I guess high comp pistons x 8 + amg tax will be very expensive. He would always deck the head, but the gains in static CR will be minimal (in the tenths).

I didn't know until I brought mine also :(

Not much man there just upgraded to a better material / design

Maybe a extra 500 rpm

Every little bit helps

I'd love an extra 400 rpm, let alone 500 :(

lol 500rpm more on yours would see you into the 9's :p:

The comb chamber......

Ahhh....thanks man. I didn't know that that's what that area was referred to as. I've heard of it as the bowl or dome. Same difference :)

Excited to see the final result of this! Unfortunately this serious of a job won't be added to my goodie bag list until way out of warranty. :) 😂

Pretty

What's the status of your fenders?

Having ported a set of heads when I was younger.... I did not know what I was doing and removed too much material from the intake runners, and from the comb chamber... result was loss of tq, loss of comp ratio, and poor performance.

Def need to know what you are doing, and what your goal is.

There are desireable sfc finishes on the ex and in side as wells... and comb chamber. Perhaps some of the more knowledgable mechs can chime in......

Cant' wait for your results/exp!

No he didn't touch the comb chambers but he did get work done on the throats and bowls.

No cams for now rather get a blower for the money especially after what Celicasaur is going through. I know I know it's probably the tune but still you need to get that **** fixed haha.

Non car will be going straight to the body shop after this assembly is completed. I'll be sure to post updates to my other post.

Initial goal was to break into the 500s. Might do a Magnuson kit in the future if I feel my tranny is up to the task.

im giving mine a extra 500 but only on the race tune not for the street

Im passing the line in 5th gear but i want to be passing in 4th gear

Are you using the HP tuners for tuning? I'm going to hit a local LS shop who uses it exclusively and see if they will tune my car if I continue to mod beyond bolt on tunes.
